DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] During the umbrella opening and closing detection process, the present invention improves the existing umbrella opening and closing mechanism. The original umbrella opening and closing mechanism is only a fixed-position downward pressure cylinder 13, a middle groove clamp 9 and an umbrella handle clamping mechanism 8. The three devices are on the same axis to perform umbrella opening and closing detection, and a single industrial camera is used to record and analyze the umbrella opening and closing conditions. The invention can change the way of umbrella opening and closing detection, so that the umbrella can change the angle and rotate for opening and closing detection, and through multiple industrial cameras and combined settings, it can detect the condition of the umbrella ribs during the opening and closing process in all directions and angles, so that the detection results obtained are more accurate and comprehensive. The umbrella opening and closing detection mainly detects the condition of the umbrella ribs. When the umbrella ribs are slightly bent, it means that the umbrella ribs have reached the life limit, which means that the umbrella is damaged. The industrial camera mainly detects the occurrence of subtle deformation of the umbrella ribs.

[0031] As shown in Figures 1 to 10, the present invention provides a technical solution: an umbrella opening and closing detection device, comprising a chassis 1, a lifting mechanism 2 and a servo driven mechanism 7 are respectively installed on the top of the chassis 1, a lifting member of the lifting mechanism 2 and the top of the lifting mechanism 2 are both installed with a dual-axis rotation mechanism 3, the movable end of the dual-axis rotation mechanism 3 at the top is fixedly connected to a clamping head 4, a downward pressure cylinder 13 for fixing the top of the umbrella is installed inside the clamping head 4, the output end of the dual-axis rotation mechanism 3 at the bottom is fixedly connected to a telescopic rod 5, the other end of the telescopic rod 5 and the top of the servo driven mechanism 7 are both installed with a secondary angle adjuster 6, a middle slot clamp 9 for controlling the opening and closing of the umbrella is installed on the top of the secondary angle adjuster 6 on the telescopic rod 5, The secondary angle adjuster 6 on the driving mechanism 7 is equipped with an umbrella handle clamping mechanism 8 on its top; the output end of the downward pressure cylinder 13, the clamping point of the middle groove clamp 9 and the clamping point of the umbrella handle clamping mechanism 8 are all located on the same axis; the first industrial camera 10 and the second industrial camera 12 are embedded in the top of the chassis 1, and a control panel 11 is also installed on the top of the chassis 1. A PLC controller 14 is installed inside the chassis 1. The PLC controller 14 and the control panel 11 are only one of the feasible embodiments. The corresponding industrial program can also be controlled by the PC or other industrial control systems to realize the operation of the equipment. The industrial program setting is matched according to different components, which belongs to the conventional existing technology in the field of automation and will not be elaborated here.

[0032] The system pre-collects and stores images of the ribs and canopy status of various types of umbrellas. Two industrial cameras are used to capture images of the ribs and canopy status of the inspected umbrella, including the canopy in various areas, the various components of the ribs, and the stitches connecting the canopy to the ribs. These images are then compared with the pre-collected images in the system for image recognition and comparison to collect information, such as identification and comparison of the bending angles of the rib nodes and the overlap of the canopy surface. The corresponding reporting threshold upper limit is set. When the comparison error reaches the set threshold upper limit, the system shuts down and records the data in a timely manner. This part is the conventional method of image processing by the industrial camera system and will not be elaborated on here.

[0033] It should be noted that the downward pressure cylinder 13 at the top controls the horizontal and vertical angles through the dual-axis rotation mechanism 3. After the angle of the downward pressure cylinder 13 is adjusted, the middle slot clamp 9 will follow the angle through another dual-axis rotation mechanism 3, the telescopic rod 5 and the secondary angle adjuster 6. The servo follower mechanism 7 located above the chassis 1 cooperates with another secondary angle adjuster 6 to control the position and angle of the umbrella handle clamping mechanism 8. In this way, the output end of the downward pressure cylinder 13, the clamping point of the middle slot clamp 9 and the clamping point of the umbrella handle clamping mechanism 8 are all located on the same axis to ensure the stability of the installation and opening and closing of the umbrella.

[0034] The dual-axis rotation mechanism 3 includes two upper and lower parallel assembly frames 301, and a half-tooth gear 302 is rotatably connected between the two assembly frames 301. The non-toothed outer wall of the half-tooth gear 302 is fixedly connected to a connecting block 303, and the other end of the connecting block 303 is fixedly connected to a protective cover 306. The inside of the protective cover 306 is rotatably connected to a rotating sleeve 308 through a support bearing 307. The outer wall of the rotating sleeve 308 is provided with matching teeth 309. A secondary motor 310 is installed on the side of the protective cover 306. The output end of the secondary motor 310 passes through the protective cover 306 and is fixedly connected to a tooth roller 311 adapted to the matching teeth 309. A primary motor 304 is installed on the top of the assembly frame 301. The output end of the primary motor 304 passes through the top of the assembly frame 301 and is fixedly connected to a driving gear 305 meshing with the half-tooth gear 302.

[0035] It should be noted that the dual-axis rotating mechanism 3 can adjust the angles in the horizontal and vertical directions. The cooperation of the primary motor 304 to drive the active gear 305 and the half-tooth gear 302 can realize wired control of the horizontal angle of the gap. The cooperation of the secondary motor 310 to drive the active gear roller 311 and the rotating sleeve 308 can realize arbitrary changes in the vertical angle. However, during actual operation, the horizontal angle change of the dual-axis rotating mechanism 3 equipped with the downward pressure cylinder 13 does not exceed 20°, and the vertical angle change does not exceed 15°, otherwise the middle groove clamp 9 and the umbrella handle clamping mechanism 8 will be difficult to adapt.

[0036] The lifting mechanism 2 includes a cover frame 201, the bottom of the cover frame 201 is fixedly connected to the top of the chassis 1, at least two electric screws 202 are installed inside the cover frame 201, the front of the cover frame 201 is fixedly connected to a protective plate 206, the outer wall of the electric screw 202 is commonly threadedly connected to a slider 204, the slider 204 passes through the front of the protective plate 206 and is fixedly connected to a supporting profile 205, the other end of the supporting profile 205 is connected to one of the dual-axis rotating mechanisms 3, the top of the cover frame 201 is fixedly connected to a top plate 203, and the other dual-axis rotating mechanism 3 is connected to the top plate 203 through the profile.

[0037] It should be noted that the lifting mechanism 2 drives the slider 204 to move up and down through the rotation of the lead screw, and cooperates with one of the dual-axis rotation mechanisms 3, the telescopic rod 5 and one of the secondary angle adjusters 6 to achieve the spatial positioning of the middle slot clamp 9.

[0038] The chassis 1 includes a box body 101, an arc-shaped groove 102 is opened on the top of the box body 101, and the servo driven mechanism 7 includes a servo motor 701, which is installed in an embedded manner at the center of the arc-shaped groove 102 of the box body 101. The output end of the top of the servo motor 701 is fixedly connected to a rocker arm 702, and an angle-adjustable accompanying camera 15 is installed on the upper surface of the rocker arm 702. The other end of the rocker arm 702 is fixedly connected to a barrel seat 704, and a slide 703 is fixedly connected to the bottom of the barrel seat 704. A guide wheel is provided at the bottom of the slide 703 to slide inside the arc-shaped groove 102. A rotating motor 705 is embedded in the top of the barrel seat 704, and the output end of the rotating motor 705 is connected to one of the secondary angle adjusters 6.

[0039] It should be noted that the center of the arc groove 102 is on the same vertical line as the horizontal rotation center of the dual-axis rotating mechanism 3 on which the downward pressure cylinder 13 is installed, so that the first horizontal position change can be performed following the angle change of the downward pressure cylinder 13, and then the umbrella handle clamping mechanism 8 is spatially positioned using the rotating motor 705 and another secondary angle adjustment. The accompanying camera 15 on the rocker arm 702 can follow the position change of the servo follower mechanism 7 to follow the shooting.

[0040] The clamping head 4 includes a connecting head 401, one end of which is fixed on the dual-axis rotating mechanism 3 located above, and the other end of the connecting head 401 is fixedly connected to a clamping claw 402, and a gasket 403 is fixedly connected to the inside of the clamping claw 402. The downward pressure cylinder 13 is limited inside the gasket 403, and a first infrared emitter 404 is provided on the side of the clamping claw 402. A second infrared emitter 805 is provided on the umbrella handle clamping mechanism 8, and an infrared sensor 906 is provided inside the middle groove clamp 9. The first infrared emitter 404 and the second infrared emitter 805 cooperate with the infrared sensor 906 to realize the positioning of the output end of the downward pressure cylinder 13, the clamping point of the middle groove clamp 9 and the clamping point of the umbrella handle clamping mechanism 8.

[0041] It should be noted that the clamping claw 402 on the clamping head 4 has a structure similar to a throat clamp and can use bolts to fix the downward pressure cylinder 13. The connecting head 401 at the bottom of the downward pressure cylinder 13 connected to the top of the umbrella is rotatable. To facilitate positioning detection, the first infrared emitter 404, the second infrared emitter 805, and the infrared sensor 906 cooperate with each other. Through the irradiation points of the two infrared emitters on the infrared sensor, it can be determined whether the downward pressure cylinder 13, the middle groove clamp 9, and the umbrella handle clamping mechanism 8 are on the same axis.

[0042] The secondary angle adjuster 6 includes a base frame 601, a rotating shaft block 602 is provided on the side of the base frame 601, and a rotating seat 605 is provided at both ends of the rotating shaft block 602. An axial motor 603 is embedded in the rotating shaft block 602, and the output end of the axial motor 603 is fixedly connected to a connecting piece 604. One end of the rotating seat 605 is provided with an adapter hole adapted to the connecting piece 604. Two parallel side frames 606 are fixedly connected to the top of the rotating seat 605, and a vertical motor 607 is installed on one of the side frames 606. The output end of the vertical motor 607 passes through the side frame 606 and is fixedly connected to a pin roller 608.

[0043] It should be noted that the secondary angle adjuster 6 controls the angle of the entire rotating seat 605 through the axial motor 603, and uses the vertical motor 607 to control the angle of the device installed on the latch roller 608. Holes for the latch roller 608 to adapt are provided on the umbrella handle clamping mechanism 8 and the middle slot clamp 9.

[0044] The umbrella handle clamping mechanism 8 includes an adapter seat 801 adapted to the secondary angle adjuster 6, the top of the adapter seat 801 is fixedly connected to a mounting seat 802, one side of the top of the mounting seat 802 is fixedly connected to a double-headed cylinder 806, the output ends of the double-headed cylinder 806 are respectively fixedly connected to mutually adapted clamps 807, a one-way cylinder 808 is installed on the other side of the top of the mounting seat 802, the output end of the one-way cylinder 808 faces the clamp 807 and is fixedly connected to a pin 809 for opening the umbrella, and the bottom of the mounting seat 802 is fixed. An L-shaped frame 803 is fixedly connected, and a locator 804 is provided on the top of the L-shaped frame 803 below the chuck 807. The locator 804 includes a positioning cylinder 810. The top of the positioning cylinder 810 is rotatably connected to a positioning head 811. The outer wall of the positioning head 811 is fixedly connected to a gear sleeve 812. The top of the outer wall of the positioning cylinder 810 is fixedly connected to a connecting frame 813. An adjusting motor 814 is installed on the top of the connecting frame 813. The output end of the adjusting motor 814 is fixedly connected to an adjusting gear 815 that meshes with the gear sleeve 812.

[0045] It should be noted that, during operation, the umbrella handle clamping mechanism 8 determines its position through the servo follower mechanism 7 and the secondary angle adjustment mechanism, and then fixes the umbrella handle position through the clamp 807. A switch is provided on the umbrella handle of the automatic umbrella, and the switch needs to be aligned with the position of the ejector pin 809. The ejector pin 809 is driven by the one-way cylinder 808 to open and close. The clamp 807 clamps the locator 804 at the bottom of the umbrella handle and cooperates with the downward pressure cylinder 13 to fix the position. When the umbrella needs to be rotated at a certain angle, the clamp 807 needs to be released to allow the adjustment motor 814 on the locator 804 to drive the positioning head 811 to rotate at a certain angle, thereby realizing the angle change. Since the automatic umbrella has buttons that need to be controlled, generally, when detecting the automatic umbrella, the umbrella is not rotated but only the angle is adjusted.

[0046] The middle slot fixture 9 includes an assembly head 901 adapted to the secondary angle adjuster 6. A pull sensor 902 is fixedly connected to the side of the assembly head 901. A double-outlet air cylinder 903 is fixedly connected to the top of the pull sensor 902. The output ends on both sides of the double-outlet air cylinder 903 are respectively fixedly connected to end frames 904. The other ends of the end frames 904 are respectively installed with mutually adapted fixture heads 905.

[0047] It should be noted that the middle slot clamp 9 generally controls the opening and closing of the umbrella, and the opening and closing of the umbrella is performed by moving the middle slot clamp 9 up and down.

[0048] By collecting human data on the forces during the opening and closing rotation of different types of umbrellas, a physical mechanical analysis is conducted, and then the parameters of the electric screw 202, the first-level motor 304, the second-level motor 310, the axial motor 603, the vertical motor 607, the servo motor 701, the rotary motor 705, the double-headed cylinder 806, the one-way cylinder 808, the positioning cylinder 810, the adjustment motor 814, the double-outlet cylinder 903, and the accompanying motor 15 are set accordingly to simulate the movements, speeds, and forces of manual opening and closing of an umbrella, and realize automatic intelligent detection of fatigue resistance of preset different types of umbrellas, thereby reducing the situation where umbrella failures due to excessive speeds, excessive forces, etc., resulting in inaccurate test results and large errors, and effectively solving the problems existing in the laboratory regarding manual inspection of umbrellas.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is limited by the accompanying embodiments and their equivalents.
